>Description:
Using the latest build of ogle with /dev/acd0 caused
the latest panic
(backtrace below). I think the same sort of panic
has occured when
I tried playing CD's on this drive as well. It looks
like some sort of
race because these panics aren't persistent but seem
to happen
when I start up cdcontrol or ogle too quickly. Just
a guess. I have
another backtrace for CD playback with an older
kernel.
